Option 2. 
shows the correct way to use the quadratic formula to solve the given equation.
Step-by-step explanation:
Step 1:
For an equation of the form 
the solution is 
.
Here a is the coefficient of 
, b is the coefficient of x and c is the constant term.
can also be written as 
Comparing 
with , we get that a is 1, b is -4 and c is -21.
To get the solution, we substitute the values of a, b, and c in .
Step 2:
Substituting the values, we get
This is option 2.

Answer:
see below
Step-by-step explanation:
m+6/3 = -8
Simplify the fraction
m+2 = -8
Subtract 2
m+2-2 = -8-2
m = -10
or
(m+6)/3 = -8
Multiply each side by 3
m+6 = -8*3
m+6 = -24
Subtract 6
m+6-6 = -24-6
m = -30
